SMUT-MACI-IINE.

Specification of Letters Patent No. 24,086, dated May 24, 1859.

To @ZZ whom 'it may concern:

Be it known that I, E. BARNHART, of Shippensburg, in the county of Cumberland and State of Pennsylvania, have invented a new and Improved Smut -Machineg and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming part of this specification, in which- Figure 1, represents a vertical central section of a smut machine constructed according to my invention. Fig. 2, is a horizontal section of ditto, the line in Fig. 1, indicating the plane of section. Fig. 3, is a section of the rotary disk and shell, taken in the line y, y, in Fig. l, and looking up from below. Y

Similar letters of reference in the 3 views indicate corresponding parts.

This invention consists in arranging in a hollow cylinder with fluted top and sides a rotary disk the surface of which is also lluted and to which a cylindrical fluted shell is attached, which surrounds t wings placed at the under side of the disk so that the wheat or grain as it passes through the funnel on the disk is spread in all directions by means of the fluted surface of the same assisted by the uted top and sides of the hollow cylinder and by the -uted shell, and that when so spread it is exposed to the blast created by the wings at the under side of the disk so that the largest part of the dust and chaff is thrown out by the force of this blast before the grain enters the fan cylinder in which it is exposed to a second and more powerful blast so that all the dirt and chaff are separated from the grain merely by the action of the blast created by the two fans.

To enable those skilled in the art to fully understand, use and constructmy invention I will proceed to describe it.

A, is a frame constructed of wood and sufficiently strong for the purpose, and arranged in the center of its bottom is a step a, and in the central part of its top a ournal box Z), which form the bearings for a vertical arbor B, to which a pulley C, is rigidly attached and which receives a quick rotary motion from some source. Firmly secured to the upper part of the arbor B, is the disk D, which is fluted on its upper surface, as clearly represented in Fig. 2, and to which a fluted shell E, is attached, the outer diamp eter of which Ais equal to the diameter of arbor B, and this cylinder is of considerably larger diameter and it is also wider than the disk D, so that this latter and the shell E, rotate therein without touching either top or bottom of the cylinder, and plenty of room is left between the outside of the shell E, and the inside of thel cylinder F,

`and so that the blast created by the wings c, can escape freely from under the shell E. rlhe cylinder F, is provided with an opening CZ, in its side and a spout 6, is attached thereto which serves to carry off the chaff and dust which are separated from the grain by the action of the wings c, and another central opening is cut into the bottom of the cylinder F, which serves to let the grain out to the fan cylinder G, which rests on a platform f, in the frame A, and which is constructed in the usual manner, having a series of wings g, which are rigidly attached to and rotate with the arbor B, and which are surrounded by the cylindrical shell G, from which a spout Zi, leads into a channel I-I, the upper part of which is divided by a slide z', and which is closed on the top and provided with outlets z', Z0, and Z, the outlet Z,

being at the bottom of the channel for the the dust and chaff.

The slide I, serves to regulate the action of t-he blast, and if it is pushed up entirely the full blast from the pan escapes through the openings vl, and le, but if the action of the blast is found to be too powerful, the slide I, is drawn down so that the opening Z, is brought in communication with the spout Zt, of the fan cylinder G, whereby the blast is -divided and its action is rendered less effective. But if the slide I, is taken out altogether, the blast from the spout h, goes right straight out through theopening Z, and its effect is at its maximum.

The operation is as follows: Vheat or some kind of grain is introduced on the disk E, by the funnel Gr', and as it touches between the iuted sides of the cylinder and T the shell E, Where it is exposed to the blast created by the Wings o, under the disk D, and the lighter particles of dust and chaff contained in the grain are driven out by the spout e, While the good grain inixed with the heavier parts of the dirt and challl is discharged into the fan cylinder Gr, Where it is exposed to a second more powerful blast created by the Wings g, and by this second blast, the efect of which is regulated by the slide I, all the dirt and chai are driven out by the openings 7c, and Z, in the channel H, and the good grain is discharged through the opening z'. By these means I am enabled to clean the grain perfectly in a very short time and Without any Waste. What I claim as new and desire to secure by Letters Patent, is: The disk D, arranged with the fiuted shell E, and with the Wings c, to operate in combination With the fiuted cylinder F, Which is provided With a spout e, substantially as and for the purpose specified.
